Multi-carrier frequency hopping spread spectrum system with girth-six low-density parity-check codes
(Institute of Electrical and Electronics Engineering (IEEE), 2009-03-14)
In this paper, a multicarrier frequency hopping spread spectrum (MCFH-SS) system with girth-six low-density parity-check (LDPC) codes is developed as forward error correction scheme to improve its anti-jamming (AJ) ...
Design and simulation of a modified block transmission system with pre-coding
(Institute of Electrical and Elctronics Engineering (IEEE), 2009-03-14)
This paper presents a simulation study for a new block transmission system that depends on sharing the equalization process between the receiver and the transmitter. The transmitter share will be 75% of the signal processing, ...
Row division method to generate QC-LDPC codes
(Institute of Electrical and Elctronics Engineering (IEEE), 2009-05-24)
To cut down the hardware implementation cost this paper presents an efficient method to construct large girth Quasi-Cyclic low density parity check (QCLDPC) codes. The row groups are paired two times the row weight, which ...
Reduced complexity optimum detector for block data transmission systems
(The Institute of Electronics, Information and Communication Engineers, 2009-12-10)
Block Data Transmission Systems (BDTS) are used in high-speed wireless communication systems with time dispersive channel characteristics. In such systems, blocks of data are separated by zeros to mitigate the effect of ...
Hilbert transform of FFT pruned cross correlation function for optimization in time delay estimation
(Institute of Electrical and Electronics Engineering (IEEE), 2009-12-15)
Measuring delay using cross correlation technique with signals that are corrupted by noise and are received at two spatially separated sensors often result incorrect measurement. This paper presents a new technique that ...
